What this article shares with you is about the advantages and disadvantages of sqlserver, Mysql and Oracle databases. The editor thinks it is very practical, so I share it with you to learn. I hope you can get something after reading this article.

1. Sqlserver

Advantages:

Ease of use, scalability for distributed organizations, data warehouse functions for decision support, integration closely related to many other server software, good performance-to-price ratio, etc.

It brings flexibility to data management and analysis, allowing units to respond calmly in a rapidly changing environment, thus gaining competitive advantage. From a data management and analysis perspective, it is important to convert raw data into business intelligence and to take full advantage of the opportunities presented by Web. As a complete database and data analysis package, SQLServer opens the door for the rapid development of a new generation of enterprise business applications and for enterprises to win the core competitive advantage. As the record holder of the important benchmark scalability and speed award, SQLServer is a database product with full Web support, providing core support for Extensible markup language (XML) and the ability to query on Internet and outside firewalls

Disadvantages:

Openness: SQL Server can only run on windows without the slightest open operating system stability is very important to the database Windows9X series of products focus on desktop applications NT server is only suitable for small businesses, and the windows platform is very limited in reliability, security and scalability, such as unix, time-tested, especially for large databases.

Scalable parallelism: SQL server parallel implementation and coexistence model is mature and difficult to handle increasing number of users and limited scalability of data volumes

Security: no security certificate has been obtained.

Performance: SQL Server has good performance when it is multi-user

Client support and application mode: client support and application mode. It only supports the windows S mode, and the SQL Server Cpact S architecture only supports windows customers to connect with ADO, DAO, OLEDB and ODBC.

Usage risk: SQL server completely rewrites the code after a long period of testing, breaking delays, and many features take time to prove and are very compatible.

II. Oracle

Advantages:

Openness: Oracle can run on all major platforms (including windows) to fully support all industry standards and adopt a fully open strategy to enable customers to choose suitable solutions to fully support developers.

Scalability, parallelism: Oracle parallel servers extend windownt capabilities by enabling group nodes to share work in the same cluster. WindowsNT can meet the needs of users to move databases. UNIXOracle parallel servers have a high degree of integration for all kinds of UNIX platform clustering mechanisms.

Security: obtain the highest certification level of ISO standard certification.

Performance: high Oracle performance to keep world records for TPC-D and TPC-C on open platform

Client support and application mode: Oracle multi-level network computing supports a variety of industrial standards for ODBC, JDBC, OCI and other network customer connections

Use risk: Oracle's long-term development experience is fully backward compatible and widely used with low risk.

Disadvantages:

The requirement of hardware is very high.

The price is relatively high.

Management and maintenance is more troublesome.

The operation is complicated and requires high technical content.

III. MySql

Advantages:

Small size, high speed, low total cost of ownership, open source

Support for multiple operating systems

Is an open source database that provides interfaces that support multi-language connection operations

The core program of MySql adopts complete multithreaded programming. Threads are lightweight processes that can flexibly provide services to users without too many system resources. MySql implemented in multithreading and C language can easily make full use of CPU.

MySql has a very flexible and secure permissions and password system. When customers connect to the MySql server, all password transfers between them are encrypted, and MySql supports host authentication

Support ODBC for Windows, support all ODBC 2.5functions and many other functions, you can use Access to connect to the MySql server, so that the application can be extended

Support for large databases, can easily support tens of millions of records of the database. As an open source database, it can be modified for different applications.

With a very fast and stable thread-based memory allocation system, you don't have to worry about its stability.

MySQL also provides a high degree of diversity, providing many different user interfaces, including command line client operations, web browsers, and a variety of programming language interfaces, such as Category Perl, Java, PHP, and Python. You can use a pre-packaged client, or you can simply write an appropriate application yourself. MySQL can be used on platforms such as Unix,Windows and OS/2, so it can be used on personal computers or servers

Disadvantages:

Hot backup is not supported

The biggest disadvantage of MySQL is that its security system is mainly complex rather than standard, and it only changes when mysqladmin is called to reread user permissions.

There is no stored procedure (Stored Procedure) language, which is the biggest limitation for programmers accustomed to enterprise databases

The price of MySQL varies with platform and installation. Linux's MySQL is free if it is installed by the user or by the system administrator rather than by a third party, while the third option must pay a license fee. Unix or Linux self-installation is free of charge, Unix or Linux third-party installation fee

These are the advantages and disadvantages of sqlserver, Mysql and Oracle databases. The editor believes that there are some knowledge points that we may see or use in our daily work. I hope you can learn more from this article. For more details, please follow the industry information channel.
